Re: vertical line on screen

Hi, This is a problem that's far too common among flat-panel and projection LCD TV's?and it's generally known as "vertical banding." If the lines are there all the time or intermittent but in the same location it is an indication of a bad panel. The panel driver can also be the cause of this symptom. Samsung panels have had issues with the connector that carries the LVDS signals to the panel itself, this is not serious and can be resolved and little cost. These faint vertical bars (often most apparent when the screen is totally dark or displaying a solid background, like the sky) are defects that occur during the manufacturing process, and while the worst offenders are typically screened out, many more make it to store shelves. Since you've pinpointed the banding and it's driving you nuts,also its under warranty, call the manufacturer and demand a replacement; in most cases, they'll capitulate and send you a new set, although you'll probably have to go to the trouble of packing and shipping back your defective TV (make sure the manufacturer covers your shipping costs). Regards sreejith

Sorry but you have a bad panel. Repair cost is prohibitive. The T-con was a good choice, but is the last step to the panel.

The SONY LCD TV is 2 1/2 Years old about 6 months ago I noticed a very light pink 3in vertical line, now after the tv is on for about 30 to 45 min the line is black. does any one have a clue how to fix...

The line or dots on an LCD screen are because of dead pixels and tolerable upto a certain limit as per policy of the manufacturer. But line is not permissible and should be changed in the warranty support. The isssue you are reporting is the vertical line and the the film is to be changed. So if the set is not in warranty it might be a big expense as there is no way to fix it at home.

Vertical black line on the screen of my 42" Magnavox flat panel lcd tv

I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.
